Title: Winding machine with individual winding stations for the winding of preferably narrow material webs, especially made of plastic, paper or the like
Inventor: DUEPPENGIESER DIETER
IPC: B65H18/08
Filed: 1993-02-11
Abstract: The invention relates to a winding machine with individual winding stations for the winding of preferably narrow material webs, especially made of plastic, paper or the like, with slides (3) which are arranged in pairs in the region of each individual winding station (1), each have a winding arm (8) and serve for mounting a winding tube (14) or winding roll (15) and which, via a linkage (16) mounted in an articulated manner on a common adjusting block (17) movable essentially parallel to the slides, are adjustable on the supporting crossmember (6) independently of the adjusting block (17) for the clamping and release of the winding tube (14) and together with the adjusting block (17) for positioning the slides (3). As a result, whilst preserving a modular design, both a rapid positioning of the slides (3) and a perfect control of the opening and closing movement for changing the winding tubes are obtained in a comparatively simple way at a very low outlay in terms of construction, without the clamping force exerted on the winding tube being varied during the positioning. <IMAGE>

Abstract: In a control device for electric tools, in particular for electric hand tools such as (multi-speed) hand drills, drilling and percussion hammers, screwdrivers and the like, it is proposed, to arrest the tool spindle (16) (lock function) by positive engagement, to mount in an actuating element (20), e.g. a turning knob, which is accessible from outside and manually adjustable, on the tool housing a slide (32) which is itself additionally movable in the radial direction and, in the spindle-arresting position, arrests the spindle rotational movement by means of an arresting member (35) actuated by it, and in this spindle-arresting position the rotatable actuating element at the same time defines an idle-running position in the transmission connection between driving electric motor and spindle. <IMAGE>
Patent DE-4308297-A1 (DE)
Inventor: OBERTRIFTER BERND DR
IPC: F15B21/045
Filed: 1993-03-16
Abstract: A flow control valve, in particular for hydraulic pressure media, has an effective cross-section for the pressure media that is variable as a function of temperature. In order to achieve a considerable variation of cross-section with a compact design, the flow control regulator is equipped with a memory element made of a metal alloy having a reproducible memory effect, by means of which the effective cross-section can be changed by a change of shape of the memory element caused by a change in its crystalline structure within a narrow temperature range. Such a flow control valve is used in a particularly advantageous manner in a regulating or controlling circuit of a hydraulic pump, for pilot controlled distributing valves, pressure valves, proportional control valves and flow control valves, for regulation and injection in compression and spark ignition.

Title: Milling machine, its use, and a surface-machining method
Inventor: DORSCH JOACHIM
IPC: B23Q39/02
Filed: 1993-04-17
Abstract: The invention relates to the use of a milling machine with milling head (10) and milling feed unit (18). The milling head has a milling spindle (16) which can be motor-driven about a spindle axis (14) and is intended for accommodating a tool (40, 42, 44), while the milling feed unit (18) has a rotary table (24), which can be rotated by motor about a rotary axis (22), for the rotational infeed of a workpiece. In order to permit accurately centred milling and turning, the milling machine can be temporarily turned into a lathe with a tool turret. This is effected by virtue of the fact that the milling spindle (16) can be fitted with a turret plate (42) carrying several turning tools (44) arranged at angular distances from one another and can be restrained and/or locked on the milling head in various angular positions about the spindle axis (14), and that the rotary table (24) can be driven like a lathe chuck with increased rotational frequency about the rotary axis (22) compared with the rotational infeed during milling. <IMAGE>

Title: Cutting-free appliance
Inventor: NICKEL HANS DIPL ING
IPC: F16D59/02
Filed: 1993-05-03
Abstract: A cutting-free appliance comprising a drive motor, a cutting tool fastened on a shaft and a centrifugal clutch arranged between the drive motor and shaft. In order, during the idling or stopping of the appliance, to reduce the follow-up time of the cutting tool necessitated by the rotating mass, the output-side element of the centrifugal clutch is connected to a break drum which is loaded by a friction element. A spring causes the automatic application of the brake, and in order to release it the spring has to be tensioned. In order to make it easier to handle the cutting-free appliance, it is proposed that the means for releasing the brake comprise a servo-drive and a switching device for activating the servo-drive.

Abstract: A linear guide unit consists of a guide rail (1) having a plurality of roll body tracks (3), a guide carriage that is mounted for longitudinal displacement on the guide rail (1) by means of roll bodies and that has a fixing surface facing away from the guide rail (1) and a damping element that is arranged in front of or behind the guide carriage in the direction of displacement and that takes the form of a slide (4) encompassing the guide rail (1) and with it forming a damping gap (7). The inner contour of the slide (4) runs essentially parallel to the profile of the guide rail (1). The slide (4) also has a fixing surface (5) facing away from the guide rail (1). The invention provides that the damping gap (7) is completely filled with an electrorheological liquid, the guide rail (1) and the slide (4) forming an electrode pair which is connected to an electrical voltage source (11) for generating an electrical field to control the viscosity of the fluid. Alterning the applied voltage enables one to change the viscosity of the liquid in the damping gap (7) and thus the damping behavior of the slide (4).

Title: Higher speed ring spinner achieving wear redn., better yarn quality
Inventor: STALDER HERBERT DR
IPC: D01H7/60
Filed: 1994-11-23
Abstract: A ring spinning machine has a bevelled flange (11) and ring (1) formed by a base on the ring frame and a bearing part (12) with beading (12') to secure the revolving runner (2). Their dimensions are so chosen that the bevelled flange forms a tapered, truncated cone of inner diameter (D) between 32 and 46mm, where the bearing surface (13) has a mean tilt (alpha) w.r.t. vertical of 25 to 35 deg. After less than an hour's run-in the bearing surface (13), so curved on the inside of the bearing part (12), forms a 2mm min. line of touch with the revolving runner (2) pulled by the spinning yarn.  In textile ring spinning. Bevelled flange ring spinning is known to offer reduced wear and tear and increased stability of runner movement. If the flange beading is two weak the runner tends to come upright because of the centrifugal effect, jumping between two contact points on the ring and leading to instability. On the other hand a beading which is too strongly curved, i.e. R2 less than 20mm, makes contact at only one point leading to excessive abrasion. The present soln. achieves higher spin speeds and simultaneous reduction of wear and tear of ring and runner. Yarn quality is also improved, breakages reduced while early failure of the runner no longer occurs.
